compute_wcss: Compute Whithin-Cluster Sum of Squares

In drisso/mbkmeans: Mini-batch K-means Clustering for Single-Cell RNA-seq

Compute Whithin-Cluster Sum of Squares

Description

Given a vector of cluster labels, a matrix of centroids, and a dataset, it computes the WCSS.

Usage

compute_wcss(clusters, cent, data)

Arguments

clusters	numeric vector with the cluster assignments.
cent	numeric matrix with the centroids (clusters in rows, variables in columns).
data	matrix-like object containing the data (numeric or integer).

Value

A numeric vector with the value of WCSS per cluster.

Examples

data = matrix(1:30,nrow = 10)
cl <- mini_batch(data, 2, 10, 10)
compute_wcss(cl$Clusters, cl$centroids, data)
